USB Relay

The R130PL_USB USB Relay is equipped with firmware built into the board that will allow you to send commands to the board to
energize the relay on the board. The USB interface will allow you to connect the board to the USB port on your computer.
The board will mount as a virtual COM port.

R130PL_USB The Ideal Choice

The R130PL_USB USB Relay allows you to program in almost any language and has the ProXR Command Set, the industry leading
command set for sending commands to control relays and read the inputs on the board.

Industry Leading Command Set
- Send Specific Commands to Trigger Relays
- Trigger Any or All Relays
- Program in Almost any Language
- Read 0 to 5 Volt Sensors

Mounts as a COM Port

This ProXR series controller connects to the USB port of your computer and will mount as a COM port on your PC. Once powered up, the controller waits for a command. A command consists of a few bytes of data in numerical format usually between 2 and 6 bytes. Once the command has been received, the controller processes the command, and sends you back ASCII character code 85 to signal the completion of your command.

ZUSB Modules

This board is equipped with a ZUSB Module. The ZUSB communications module adds USB communications to the board. The ZUSB module is powered from the USB port of your computer and includes a 6' USB Cable. The board itself will require 12 volts of power and can be hard wired or you can purchase a "wall wart" type Power Supply at checkout.

Induction Capacitors

Perhaps the most overlooked aspect of relay control is proper handling of inductive loads. Inductive loads can best be defined as anything with a magnetic coil, such as a motor, solenoid, or a transformer. Controlling a inductive load using this relay controller requires the use of induction suppression capacitors. The purpose of this capacitor is to absorb the high voltages generated by inductive loads, blocking them from the contacts of the relay. Without this capacitor, the lifespan of the relay will be greatly reduced. Induction can be so severe that it electrically interferes with the microprocessor logic of our controllers, causing relay banks to shut themselves down unexpectedly. In the case of USB devices, customers may experience loss of communications until the device is reconnected to the USB port. Capacitors that we offer are available at checkout, for more information view our Induction Suppression Video.

Induction Solutions

Even with capacitors in place, the possibility does exist that capacitors will not suppress enough induction to prevent periodic communications loss. Testing is required in these applications. If problems persist, other communications mechanisms must be considered. If USB is required, an RS-232 communications module will allow RS-232 communications between your PC and controller with no complications. A USB to RS-232 adapter can be used in combination with the RS-232 controller. The RS-232 communications format effectively blocks induction to safe levels for a USB to RS-232 adapter to function without errors (look for "RS232 Relays" under Shop by Interface on the left navigation). If the problem persists after you purchase a USB board you can change out the USB module for an RS-232 or wireless module easily.

ProXR Lite Relay

In this tab we'll take a look at the board design itself. The ProXR Lite series controllers are machine manufactured for a highly accurate and reliable design. Fully tested before they leave the production facility each ProXR Lite controller is ready to stand up to rigorous demands from heat, cold or vibration. The best test of all is the numerous boards in the field from customers all over the world in all sorts of conditions. Take it from us, these controllers will hold up!

Not Expandable

Unlike it's big brother, the ProXR Series, the ProXR Lite series controllers are NOT expandable. The firmware still thinks 256 relays are available but the relay portion of the controller only responds to the first 1, 2, 4 or 8 relays in Bank 1.

Full ProXR Enhanced Firmware Installed

This board has ProXR Firmware installed that responds to the full ProXR Command Set - it's just not expandable. The ProXR Firmware is the industry leading firmware for controlling relays with more commands and functionality than any other board on the market. The list of commands and parameters this board is capable of is extensive. ProXR Enhanced is the newly released enhance version of the ProXR Firmware with more commands, more functionality and better control than ever before! For a detailed list of all the commands with descriptions see our ProXR Enhanced Command Set.

Essential Power Requirements

Applying Good clean power to the board is essential for the operation of the board. Not only for the switching of the relays but the firmware that processes the commands. Without good steady clean power from a regulated power supply the board simply will not function correctly. All boards on the site require 12 VDC power. The PWR12 US power supply is a 120VAC to 12VDC 1.25A 60Hz regulated power supply and it plugs into the barrel connector on the board. The output connector is a 2.1mm I.D. x 5.5mm O.D. x 9.5mm Female R/A barrel connector. We also carry an international power supply with interchangeable adapters for international customers.

Read Analog Sensors

We did NOT skip the Analog Input portion of the ProXR Lite. All ProXR Lite controllers offer a 8-Channel 8/10-Bit Analog to Digital Converter in addition to relay control. Read and control from 8 sensors per board from 0 to 5 volts! A/D inputs are ideal for reading the on/off status of switches. Simply position the Up/Down jumper in the UP Position and connect a switch between input and ground, software may then be used to monitor the contact closure status of your switch. AD inputs can also be used for reading variable resistance signals. Position of Up/Down jumper should also be in UP position for reading variable resistance signals. The board will then will return a value between 0-255.

SPST Relay Installed

This device has SPST relays installed. SPST Single Pole Single Throw Relays simply connect two wires together. The Common (COM) is the
moving part of the relay that comes in contact with the Normally Open (NO) when the coil to the relay is energized. Wiring is done directly to the Relay terminals using a common 1/4" quick disconnect terminal. To the left is a picture of the connector that will connect to the relay.

2-Million Cycles

ProXR series controllers are designed for long life, you should expect to get years of service from your controller and literally 2-million cycles from the relays on board.

Relay Timer

Time Schedule Control

Relay Timer Software allows you control each relay independently from a time schedule you create! The software can be installed on a server or PC and uses the computers time for an accurate relay control.

Control relay in recurrent time sequence

Thanks to protocol of ProXR & ProXR Lite boards it is possible to update 8 relays at one time. If speed is a requirement it only take about 30 ms to update 8 relays. In
multiple relay applications Relay Timer calculates all relays’ status together, even though each of them work separately.

Take Manual Control

You can take manual control of any relay at any time to interrupt the schedule and control a relay. Automatically switch back to Auto Mode and resume the schedule manually or set a fixed time to return to the schedule.

Quick Timer
